Screen Color mod?

[NUDEL]

hey i heard that the digis actually have an RGB screen (at least digitakt2 & digitone2), so would be cool to have a menu option to change the screencolor to something else, f.e. red

Both have a white-on-black OLED screen. They cannot show different colours.
This would require a hardware modification, meaning replacing the screen in its entirety.
